Experimental Design - Unconfounded Effects

Select the Keep selected effects unconfounded check box or click the  on the Searching for and Analyzing Designs with Two-Level Factors - Search Criterion tab in the Experimental Design module to display the Unconfounded Effects dialog, in which you select the effects of the crucial order, given the resolution, that you want to keep unconfounded. This option operates by eliminating from the search those designs with effects that are confounded with the specified effects. Because of the nature of the sets of generators that are searched (i.e., non-isomorphic sets, excluding sets where factor names are merely relabeled), the Comprehensive search of all generators option on the Searching for and Analyzing Designs with Two-Level Factors - Search Strategy tab cannot be selected when the Keep selected effects unconfounded option is used.
